Resilience to Hurricanes Is High in Mangrove Blue Carbon Forests

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

ABSTRACT Mangrove forests are typically considered resilient to natural disturbances, likely caused by the evolutionary adaptation of species‐specific traits. These ecosystems play a vital role in global carbon cycle and responsible for an outsized contribution burial enhanced sedimentation rates. Using eddy covariance data from two coastal mangrove Florida Coastal Everglades, we evaluated impact hurricanes have on forest structure function measuring recovery pre‐disturbance conditions following Hurricane Wilma 2005 Irma 2017. We determined “recovery debt,” deficit ecosystem disturbance, using leaf area index (LAI) net exchange (NEE) dioxide (CO 2 ). Calculated as cumulative deviation conditions, debt incorporated recapture all lost due disturbance. In Everglades forests, LAI returned levels within year, respiration maximum photosynthetic rates took much longer, resulting initial 178 g C m −2 at tall with limited impacts scrub forest. At landscape scale, was 0.40 Mt C, most recovered just 4 years. While high‐intensity storms could prolonged subtropical fast canopy suggests these will remain strong sinks.

Abstract We document the range expansion of Eurytium limosum (Say, 1818), a panopeid, mud crab commonly found in Florida mangroves and southeastern US salt marshes, from its historically known northern limit southern South Carolina to newly observed central North (NC) marshes.

Rapidly Changing Range Limits in a Warming World: Critical Data Limitations and Knowledge Gaps for Advancing Understanding of Mangrove Range Dynamics in the Southeastern USA

Estuaries and Coasts, Journal Year: 2023, Volume and Issue: 46(5), P. 1123 - 1140

Published: May 9, 2023

Abstract Climate change is altering species’ range limits and transforming ecosystems. For example, warming temperatures are leading to the expansion of tropical, cold-sensitive species at expense their cold-tolerant counterparts. In some temperate subtropical coastal wetlands, winters enabling mangrove forest encroachment into salt marsh, which a major regime shift that has significant ecological societal ramifications. Here, we synthesized existing data expert knowledge assess distribution mangroves near rapidly changing in southeastern USA. We used elicitation identify limitations highlight gaps for advancing understanding past, current, future dynamics. Mangroves poleward often shorter, wider, more shrublike compared tropical counterparts grow as tall forests freeze-free, resource-rich environments. The northern USA particularly dynamic climate sensitive due abundance suitable wetland habitat exposure winter temperature extremes much colder than comparable on other continents. Thus, there need methodological refinements improved spatiotemporal regarding changes structure Advancing critical foundation plant such mangroves, it provides basis anticipating preparing cascading effects climate-induced redistribution ecosystems human communities depend ecosystem services.
